how do I create an image from a tar archive in docker

Question

I have a tar archive gzip file of a docker container. How do I get the image of that docker container?

Answer 1

You can use docker load command inorder to get the image from that tar archive file. 

docker load [OPTIONS] tar file

For a better understanding you can refer to:Load an image or repository from a tar archive (even if compressed with gzip, bzip2, or xz) from a file or STDIN. It restores both images and tags.
